With these and other objects and advan tages in view the invention consists-in the construction and arrangement of the several parts which will be more fully hereinafter described and claimed, In the drawings: Figure 1 is an end ele- & gm house or ginnery showing an elevator and gin and the improved separator or eliminator disposed in the elevator between the inlet of the latter and the gin. Fig. 2 is a separator or eliminator. Fig. 3 is a longitur dinal vertical section of the separator or eliminator.

The pneumatic elevator is also supplied with asuction fan 10, as will he nnderstood. The parts just explained arewell known in the art of cotton ginnin and eed. not be particularly describ H, as the invention does not a ply thereto but consists of a separator or en'n nator 11 interposed between the exterior inlet 0.1 feed extremity of the pneumatic elevator and the separator as shown, or the :se arator or'eliminator 11 may be arranged be ween the inlet of the elevator and any with a 'n. a The separatoror'eliminator embo ying the features of the invention is clearly shown in detail by Figs. 2, 3, 4 and 5 and comprises a body 12 approximately of Y- shaped form or having upwardly and out- 'wardly extending conduits 13. which are regularly curved at their point of juncture wlth the main portion of the said body 12. The terminals of the neumatic elevator 8 7 reel ends of the upwardly and outwardly extending branches 13 by enlargements 14 of said terminals. a The top We ls of the upwardly and outwardly extending branches 13 converge and unite at a oint sufficiently below the horizontal wa of each branch 13 and far enough above the bottom 14 of the body 12 to render the separation of heavier particles or devices from the seed cotton/effective and also to rovide a chamber or receptacle :1 15 of such epth and capacity as to permit the seed cotton from whlch the heavier sub-' :1 stances or particles have been separated or eliminated-to pass from one branch 13 into the remaining branch and also allow the branch and the one end wall and a portion of the bottom wall 17 of the body 12 and the remaining branch 13 are constructed and arranged as shown by 3, 4 and 5, and each is rovided with semicylindrlcal baffles 18, t e baflles of the wall 16 being in line with the entrance branch 13 or that nearest the inlet of the pneumatic elevator so that the seed cotton when drawn through the improved device by suction strikes the wall 16 and the baflles 18 thereof and is deflected downwardly and at the same time the heavier substances or particles carried with the seed cotton are separated and caused to fall against the bottom 14, the cotton passing downwardly under the point of convergence of the top walls of the two branches or through the upper portion of the chamber 15 and is caused to strike a ainst the wall 17 and the bafiles 18 of the atter to insure the liberation and removal of any of the heavier substances which may not be fully liberated by the cotton striking against the wall 16 and battles 18 thereon.

In one end of the improved separator or eliminator at a suitable point below the oint of intersection of the top walls of the branches 13 an air inlet valve 19 is provided and readily operative to permit the entrance of air into the chamber 15 without afiecting the conveyance of the seed cotton but assisting in the deposit of the heavier substances or foreign matter carried by the seed. cotton against the bottom 14 or within the chamber 15. It will be understood that owing to the suction force exerted through the pneumatic elevator on the seed cotton the latter will strike the plate or wall 16 with considerable force and the power of the suction in the elevator might be at times sufiicient to defeat the operation of separation or elimination, but by providing the air inlet valve19 an additional current is set up in the chamber 15 in the direction of the outlet branch 13 and thus prevent any tendency of the cotton to settle toward the bottom of the chamber 15 and also materially assist in the deposit or gravitation of the heavier substancesand destroy any air eddies adjacent to. the bottom 14 or within the lower ortion of the chamber 15. It will be obvious that in view of the lightness of the seed cotton the heavier substances or particles will be reliably separated and the cotton will pass from one branch 13 into the other branch through the upper portion of the chamber 15 and thence to the usual separator or other device 7 and eventually to-the gin or gins 6. At the end of the body 12 opposite that having the valve 19 therein a suitably hinged door 20 is applied over an outlet opening 21 to permit the removal of the material collected in the chamber 15, the

door being normally held closed by a suitcover 23 to permit lnspection of the interior of the chamber'15.'

The improved separator or eliminator embodying the features of the invention will serve as an eifective auxiliary to cotton ginning machiner by reason of the removal of the heavier su stances that ma be carried into the pneumatic elevator wlth the seed cotton and. prevent injury to the saws or ginning devices and consequently increase the output of gins and also produce a materially better gradeof ginned cotton.

.It is obvious that any suitable materials may be used in the construction of the improved device, but it is preferred that the walls 16 and 17 at least be of metal of such resistance to wear as to render the improved the course of the seed cotton and at the same time cause a'separation of the foreign matter from the seed cotton.

2. The combination with acotton elevator and a gin, of a separator disposed in the elevator between the inlet extremity of the latter and the gin, the separator consisting of a depending body having inlet and outlet conduits extending u wardly and outwardly therefrom, the iniet conduit having its inner wall above the main portion of the. body provided with a plurality of transversely extending baflle devices and the one wall of the body below the conduits and adj acent to the outlet conduit also having transversely extending baflie devices in the air plane to retard and divert the course of the seedcotton and effect an elimination of the heavier matter from the seed cotton and cause such matter tobe deposited in the bottom of the body.

3. The combination with a cotton elevator and ginning mechanism, of a separator having a depending body and disposed in'the elevator between the inlet extremity of the latter and the ginning mechanism and pro vided with upwardly and outwardly extending conduits terminally connected to'v the elevator, the one conduit constituting an inlet and the other an outlet, the inlet conduit having bafile devices on the inner wall thereof above the body and the latter having aving upwardly and outwardly ex-' baffle devices on the wall thereof belotv and my hand in presence of two subscribing witadjacent to the1 outlelt condt fiit, tlllf hbody nesses.
